Log rolling adversary game device

ABSTRACT

An elongate platform comprising a length of paper tubing of arcuate cross section fitted into two longitudinal channels along the edges of a board. The platform is long enough to support two players, thereon without touching each other and is about nine inches wide. The height of the platform is substantially no greater than the radius of curvature of the arcuate tubing and may be considerably less than that radius. Cleats on the underside of board at each player station facilitate lifting the device. In an alternate embodiment the device is a solid body molded from a self skimming rigid urethane foam.

An interesting example of such a game is the art of log rolling in that while it is fun to watch, relatively few people ever have the opportunity to try their hand at it. Devices have been proposed for aquatic uses in simulation of log rolling, see, for example, Davies U.S. Pat. No. 2,931,648 and Bancroft No. 3,223,411, but as far as I know, no game device has been made available for use on land enabling, in a game analagous to logrolling, one contestant to attempt to dislodge his opponent from an unstable platform as distinct from balancing devices of which the patent to Pitkanen, U.S. Pat. No. 3,485,493, is an example.

THE PRESENT INVENTION The objective of the present invention is to provide an adversary game device that can be likened to log rolling" but is adapted for use on dry land, even indoors.

In accordance with the invention, this objective is attained with an adversary device that comprises an elongated platform that is unstable with reference to its long axis and is of such length and width that two contestants can stand thereon, one at each end, without physically contacting one another and attempt to dislodge one another by platform unbalancing movements.

THE PREFERRED EMBODIMENTS OF THE INVENTION In the accompanying drawing, there are shown preferred embodiments of the invention of which FIG. 1 is a perspective view of an adversary game device;

FIG. 2 is a section taken approximately along the indicated lines 22 of FIG. 1;

FIG. 3 is a section taken approximately along the indicated lines 3-3 of FIG. 2;

FIG. 4 is a section similar to FIG. 3 illustrating another embodiment of the invention; and

FIG. 5 is a fragmentary perspective of another game device in accordance with the invention.

The adversary game device illustrated by FIGS. 1 3 is generally indicated at and comprises an arcuate shell 1 1 that may be a lengthwise section of a relatively heavy paper tube. A platform 12 has lengthwise marginal channels 13 disposed and dimensioned to receive the edges of the arcuate shell 11 which are anchored therein as by an adhesive. Internal reinforcements 14 are provided in the areas where the contestants are to stand and each reinforcement also serves as a cleat or handle for onehanded lifting and carrying of the device. The device is finished with a suitable protective coat.

In use, the contestants initially stand, with both feet on the platform, one at each end, and without contacting each other. When each is thus positioned, he tries to dislodge the other by rocking the device' in a manner simulating log rolling making possible games of the type presently to be generally described.

While the dimensions of the devices depend somewhat on the age groups of the contestants and the degree of instability wanted, for most uses the following illustrative dimensions are satisfactory for adults and most children: length 30 inches, platform width approximately nine inches, and with a height usually approximately equal to or slightly less than the outside radius of the arcuate shell 1 l in order to prevent the platform from being too unstable.

In this connection, reference is made to FIG. 4 in which there is shown a modified form of the invention which is identical to the device just described except that its height is substantially less than the outside radius of its shell thereby rendering the platform some what more stable. As this embodiment of the device is primarily for use by small children, the other dimensions may also be smaller. In this embodiment, corresponding parts are distinguished by the suffix addition A to the appropriate reference numerals.

The embodiment of the invention illustrated by F IG. 5 is preferred for outdoor uses or institutions and is generally indicated at 15 and may be molded from a rigid foam material, preferably a self-skinning, rigid urethane foam. The supporting surface 16 of the device 15 is arcuate and while its radius may be varied as in the case with the previously described embodiments, it is slightly more than the height of the device. The upper surface or platform portion 17 of the device 15 is shown as arcuate with the radius thereof substantially greater than the height of the device.

In use, a device in accordance with the invention is placed round side down, on a suitably level and flat surface and spaced, four feet, for example, from any obstruction. Two contestants take their places on opposite ends of the device and when both are ready, each triesv to dislodge the other.

By way of example, rules of a game could provide that the first person to touch the floor on other surface with his foot or any other part of his body loses and his opponent gains one point with the winner being the first contestant to win two points. If either contestant touches the other, it is a foul and a point is awarded to the contestant who is fouled.

The devices can be used in a game to be played by any number of persons. For example, the several players form a line with the first two persons being the first contestants. The winner is challenged by the next in line with the winner and the challenger playing one game and so on at least until each person has had an opportunity to participate.
